Hi,
This is not just an issue with the Surface laptops. I have a new DELL XPS laptop running on win 10 pro with intel i7 11th gen processor with 16gb ram. I was going through the exact same issue. The screen blacks out for a moment and comes back. Also noticed the display intense apps like Netflix or games will crash the app and closes abruptly. Found the logs in event viewer and finally landed on this thread. This is some kind of display driver issue on intel laptop. Microsoft need to work with Intel to get this corrected.
